Description

FASTENER INSTALLATION SYSTEM AND METHOD
FIELD OF THE INVENTION
[0001] The present invention relates to SDS drills, and more particularly to installing fasteners with SDS drills.
BACKGROUND OF THE INVENTION

[0002] In construction, one of the most common operations is to install fasteners, such as threaded fasteners, into a receiving surface such as concrete, metal, wallboard, and so on. The operation of installing fasteners generally requires a hole to be drilled in the receiving surface, an anchor to be installed in the drill hole, and then the fastener be installed in place in the anchor within the drill hole.

[0003] Often, threaded fasteners must be installed into a surface of hard material, such as a concrete wall or floor. In this case, it is common to use an SDS
type drill, as is well known in the industry. SDS drills are rotary hammer drills that have a chuck that concurrently provides rotational and hammering motion for a retained drill bit. The drill bits have a pair of slots therein, and are inserted into and slidably retained in a specifically designed chuck system that allows for limited longitudinal displacement of the retained drill bit, as caused by a hammer-action mechanism. This specific hammering action allows power to be directly, accurately and efficiently transferred to the drill bit.

[0004] Typically, it is undesirable to actually puncture the entire thickness or depth of the concrete walls or floors in order that they serve as a complete, or nearly complete, barrier. Therefore, the drill holes are over depth less than the thickness or depth of the concrete walls or floors. Accordingly, a nut or the like cannot be engaged onto the threaded lead end of the threaded fastener. In order to ensure that the threaded fastener is securely retained in the receiving surface, an anchor such as a wedge anchor is used.

[0005] In order to install a wedge anchor into a drill hole, it is initially manually inserted up part way into the drill hole. Subsequently, a hammer is used to carefully tap the wedge anchor into place. Unfortunately, this operation partly relies on the skill and strength of the worker, and also is fatiguing. Further, it is necessary to carry around and have immediately available a suitable hammer. Also, this operation can be quite time-consuming, especially considering that the worker must use the SDS drill and the hammer alternatingly, or in other words put down one tool and then pick up the other tool for every fastener/anchor pair that is to be installed.

[0006] It is an object of the present invention to provide a method of installing a fastener into a receiving surface.
